The installation of technology in the school library is only the first step in its effective use by students. Many search engines are not intuitively obvious to users, and students often need help with searching. Systematic formal instruction in electronic search skills is necessary for awareness of library software and competence in its use. The paper focuses on the why, what, when, how, and where of teaching electronic search skills to high school students. Such instruction is necessary to justify the investment in information technology because the evidence suggests that students do not learn to be efficient users of that technology on their own. Concepts, skills, and resources used in instruction should be developmentally appropriate, and students should choose their own topics and utilize the range of thinking skills in Bloom's taxonomy. Information technology may be integrated into the curriculum through a short course for all students offered as part of library skills, computer literacy, or research skills.
